Sentinel Heartworm Availability

Sentinel is Back In Stock at VetRxDirect!

Sentinel, the popular oral heartworm and flea preventative, is once again available at your pet’s online pharmacy, VetRxDirect.

Sentinel GroupSentinel (milbemycin oxime / lufenuron) is a palatable one-a-month prescription heartworm and flea preventative pill for dogs and puppies. Sentinel also controls some intestinal parasites. See the product’s package insert and ask your veterinarian for more information.

Sentinel’s arrival on our shelves is just in time for spring. Now is the time when many dog owners make appointment with their pet’s veterinarian for spring exams, including a heartworm test. This is also a good time to ask your veterinarian if your dog should switch to sentinel or stay on his/her current heartworm preventative. Your veterinarian who has examined your pet is the best source for this information.
